corn kernel
milled corn grains where the outer covering (pericarp), germ (embryo), and tip cap

sizes
corn grits
machine that removes the pericarp, crushes the kernel, polishes the grits, and sorts
the grits into different sizes
corn mill
used to remove the germ, tip cap, and pericarp from the corn kernel
degermer
ratio of the weight of degermed corn kernels to the initial weight of the degermer
output sample, expressed in percent (%)
degermer efficiency
process of separating germ, pericarp, and tip cap from the endosperm and reducing
it into grits without soaking the corn kernels before milling
dry milling
part of the corn mill used to grind the degermed corn kernels into corn grits
